get_single_routine

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of disclosure. It only states the basic action and does not mention error handling (e.g., not found), return value format, or permissions. This is a simple get operation, but behavioral transparency is minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, straightforward sentence with no wasted words. It is front-loaded and immediately understandable, earning high marks for conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple get-by-id tool, the description is minimally adequate. However, with no annotations, no output schema, and no mention of error cases or when to use it relative to sibling tools, it leaves notable gaps. It does not clarify what happens if the routine doesn't exist, which an agent may need to know.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema only defines 'routineId' as a string with no description, so the description's 'by its Id' clarifies that this parameter is the identifier of the routine to fetch. However, it does not provide additional format details beyond what is already obvious, and schema coverage is 0%.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Get a routine by its Id' uses a specific verb ('get'), a clear resource ('routine'), and a scope ('by its Id'), distinguishing it from the sibling 'get_routines' which presumably retrieves multiple routines. It is unambiguous and directly states the tool's function.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance is given on when to use this tool versus alternatives like 'get_routines' or other get_single_* tools. The implication of 'by its Id' is present, but there is no clear context, exclusion, or alternative naming.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
